Practical Experience Gained During the First Twenty Years of Operation of the Great Plains Gasification Plant and Implications for Future Projects.

摘要

The Dakota Gasification Company's (DGC) Great Plains Synfuels Plant (GPSP) in Beulah, North Dakota has operated successfully for 20 years as the only commercial coal-to-natural gas facility in the United States. The experience gained during those 20 years has created an opportunity to benefit from a fully proven technology base. This document is intended to capture what the first 20 years of the plants operation has taught operators about a synthetic natural gas from coal production facility. This information is expected to aid in the design, construction, and operation of future coal gasification facilities. The plants success has not been achieved without some changes and alterations over its lifetime. The sources for this report, which include past technical reports and interviews with plant operators and managers, revealed that most parts of the original plant design worked well, but a few did not. Many processes in the plant have undergone redesign, repair, or improvement. These changes have made the plant much more productive, efficient, and environmentally sound than even its designers envisioned.
